About Nausea

Nausea. Most have experienced it in one form or another. Taking off and landing on an airplane, or driving on hills and curvy roads commonly cause people to feel nauseous and maybe even vomit. Carsickness, airsickness, and morning sickness are all common forms of nausea that most of us are familiar with.


Everyone from infants to the elderly experiences being nauseous. It’s a complex biological reaction to various types of stimuli and is a healthy and normal event in many cases. Nausea and vomiting is a way for the body to eject or purge unwanted, dangerous, and toxic pathogens from the stomach, but in some cases, it can become a debilitating symptom that prevents us from accomplishing basic activities in daily life.


What Causes Nausea

Medically, nausea is a nonspecific symptom, meaning that it can be caused by a number of different things. The leading causes of nausea are gastrointestinal infections and food poisoning, but the cause could also stem from beyond the stomach and GI tract.


Motion sickness in cars and planes, disequilibrium, and being pregnant are usually accompanied by some level of nausea. Medical conditions, illnesses, diseases, and medications and treatments for diseases can all also cause nausea. Signals from various systems, such as the central or peripheral nervous system and the vestibular system within the inner ear, travel to the brainstem where they activate other biological processes that induce the symptoms of nausea, such as excessive salivation and dizziness. The induced activity involves halting and reversing propulsion in the GI tract and increasing abdominal muscle contraction.  


Normal Treatments for Nausea

There are many triggers attributed to the cause of nausea and maybe, even more, medications to treat them. For most patients, it depends on what system of the body is being triggered to induce nausea, but for others, it may actually be caused by medical treatments and drugs, as such is the case with chemotherapy and HIV patients.


Reports suggest some 75 percent of pregnant women experience nausea and morning sickness during pregnancy. Most are prescribed some type of nausea medication, but recently a popular morning sickness drug’s safety has been questioned. The FDA approved the drug, Bendectin – a combination of doxylamine and pyridoxine, in the mid-1950’s. About twenty years later a series of lawsuits and studies claimed that the drug was associated with birth defects and it was voluntarily withdrawn from the American Market in 1983.


In 2013, the same combination of drugs was approved for market by another pharmaceutical company, this time under then name Diclegis. Researchers at the University of Toronto requested data from the FDA through a freedom of information act on the specific studies and trials that were used in consideration and approval of the drugs.


The researchers discovered over 200 pages of redacted information and found that 31 percent of participants in the original Bendectin trial had never completed it. “All that data could change the findings on the effects of the drugs”. Authors of a new paper reviewing the previous Bendectin study concluded that “The integrity of the data, high dropout rate, and methodological concerns mean that the prescribing of this medication should not be based on this trial”.


The Bendectin study was never even published in a scientific journal back in the 1950’s. This isn’t the first time clinical trials and studies have been suppressed, altered, or otherwise influenced by bias. Many drugs that are approved to be safe are actually a lot more harmful to the brain and body than the warning labels and pharmaceutical companies may lead consumers and doctors to believe.


How Medical Marijuana Can Help Nausea

The antiemetic, or nausea-relieving, effects of cannabis have been known for centuries. Only recently have scientists discovered why marijuana relieves nausea and other conditions so effectively. The flowering buds of cannabis produce resin rich in cannabinoids like [THC] and [CBD], and terpenes such as [Humulene] and [Pinene]. These exogenous phytocannabinoids are able to bind with specialized receptor cells in our body called [cannabinoid receptors].


Since the 1970’s scientists have been researching the effects of THC on nausea. In a study on chemotherapy patients published in The New England Journal of Medicine in 1975,  researchers determined that THC worked better at alleviating nausea caused by anti-tumor drugs better than placebos.


Since then, thanks to advancing medical marijuana law and science, new studies have reinforced the findings of old medical marijuana research. Evidence and support are mounting for the case of cannabis as an antiemetic, and it may even be more effective and safe than conventional pharmaceuticals.


A systematic review of 30 randomized, controlled trials published between 1975 and 1997 compared cannabinoids with placebo and other antiemetic medicines. Researchers concluded that patients, especially those with chemotherapy pain, preferred cannabinoids to regular nausea medications and that [cannabinoids] were more effective than traditional antiemetics.


Medical marijuana’s ratio of [THC: CBD], secondary cannabinoids, and terpene profile are all attributable to its effects. Plant-based cannabis medicines seem to be safer and work more harmoniously with the body than synthetic cannabinoids. Consult with a physician and medical marijuana professional about using cannabis to alleviate nausea. Follow the conditions links throughout this article for more information on how medical marijuana can help to treat other conditions, such as chronic pain, anxiety, muscle tension, spasms, and even arthritis, epilepsy, and Alzheimer's Disease.
